There is a rich history of exploring display shapes in designing user interfaces. Some of the relevant explorations
include volumetric displays [9], non-planar displays such as
spherical, cubic or polyhedral [3, 21, 24], displays distributed in environments [22], collocated or embedded in everyday objects [11], actuated displays that change their
shapes dynamically [7, 19, 20] and even biological displays
where the change of appearance of biological species is
used as a display modality [6, 16]. The overall goal is to
find new forms for effective information presentation, exploring novel aesthetic qualities or designing displays appropriate for specific application limitations.
